YBYWMU'Q WWW Em United States Patent 3,087,237 HINGE PINTLE EJECTOR William H. Johnson, 1412 Claiborne St, Danvilie, Va. Filed Mar. 30, 1961, Ser. No. 92493 3 Claims. (Cl. 29-267) The present invention relates to a portable manually actuata'ble wholly mechanical-type hinge pintle dislodging and ejecting device, more particularly, a specially constructed implement or device and which is expressly, but not necessarily, designed and adapted to be used on butt hinges such as are currently being used on and in conjunction with tobacco hogsheads made up of symmetrical halfsections which are operatively joined together by butt hinges. I

Stated otherwise, the concept has to do with a simple, practical and feasible tool-like device which provides an easy-to-use pintle ejector, the same serving to speed up the pintle removing step in a manner to expedite opening a hogshead, the construction being such that it promotes a saving in time and labor and ejects pins from the hinges without damage to the surfaces of the hogshead sections or the leaves of the hinges. Ordinarily, sectional hogsheads are placed on dollies in an upright position with the heads of the hinge pins up in order to make it easier to remove the pins. The present mode of accomplishing the result, not considering the advent of the instant invention, involves haphazardly knocking the pintles or pins out using hammers, hatchets and screwdrivers. Manifestly, the hinges and hogsheads are damaged from time to time. Not only this, any number of pins are banged out with such force that they are lost. Generally speaking workmen are not too much concerned with the factors of damage and loss. Therefore, the problem which has posed itself is one which calls for a practical and an acceptable solution. It follows that the herein disclosed invention offers a practical adaptation which provides a satisfactory solution.

Briefly, a preferred embodiment of the invention is that which is herein disclosed in the views of the drawing. By glancing at the drawing it will be seen that the improved hinge pin loosening and ejecting device is characterized by a portable base designed and adapted to be coordinated with and positioned properly over and in relation to the leaves and pintle-containing knuckles between the contiguous ends of said leaves, said base having predetermined portions thereof which are precisely alignable' with the knuckles and push-out-type pintle, handle means carried by said base, plunger means connected with said base and embodying a plunger with an end to line up with said pintle so that by imposing a thrust against the pintle the latter can be dislodged and forced out of the knuckles containing it, and means for forcibly moving the rod toward and from the end of the pintle with which it is engageable.

More specifically, novelty is predicated upon a base comprising a block-like body channel-shaped in crosssection with the channel lined up with the leaves of said hinge, the longitudinal walls of the channel having registering notches said notches also being coordinated and registrable with the respective ends of said pintle, and said rod being in line with and operable through said notches.

A still further improvement resides in a channel-shaped base with an outstanding handle, guide notches in the Wall of the channel, a cylindrical sleeve providing a sheath and said sheath containing a reciprocable plunger rod. The plunger rod engages the pintle and is provided with rack teeth operated by a gear having a suitable crank handle.

These together with other objects and advantages which 3,087,237 Patented Apr. 30, 1963 "ice will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a view in perspective showing a fragmentary portion of an upstanding tobacco containing hogshead, the customarily used butt hinge and showing, what is more important, the invention and how it is constructed and used;

FIGURE 2 is a view on an enlarged scale with parts in section and elevation taken on the plane of the line 22 of FIGURE 1, looking in the direction of the arrows;

FIGURES 3 and 4 are sections on the line 33 and 4-4, respectively, of FIGURE 2.

The hinge means as an entity is denoted by the numeral 6 and is a butt-type hinge construction, the leaves thereof being denoted at 8 and 10 and fastened in place at 12 on the component parts 14 and '15 of the tobacco containing hogshead (not detailed). The adjacent ends of the leaves are provided with the usual knuckles 16 and 17 containing the insertable and removable hinge pin or pintle 18. The pin as usual is provided with a head 19. These are all old or conventional parts. The invention resides in the improved device (tool or implement as it may be acceptably called). The base of the device denoted at 20 is a comparatively heavy one-piece metal block which may be said to be rectangular in plan and which is channel-shaped in cross-section, the web or body of the channel being denoted at 22 and the longitudinal flanges or side walls at 24 (FIG. 1). These flanges are provided with registering notches 26 and 28 (FIG. 2) which when the base is in use are lined up with the hinge pin and knuckles. Attached to at one end portion to the body of the base is an outstanding heavy metal handle 30. This handle may be secured atop the base by screws or equivalent fasteners 32 as shown in FIG. 3. The handle functions not only for lifting, lowering and positioning the base in coordinate relation, it contributes to the other means for orienting the plunger. This plunger comprises a reciprocable rod 34 which is shiftable in a tubular sheath or cylinder 36 which is fixed across the lower edge portion of an adapter plate 38. This plate is a simple flat member having an end portion 40 superimposed against one side of the handle and secured thereto by screws or equivalent fasteners 42. The plate has a notch cut out in one corner so that the marginal edge portions may be keyed in grooves provided therefor in cooperating surfaces of the base. The plate not only supports the cylinder or sheath and plunger rod it also serves as a support for the disk-like gear 44. This gear is bolted and pivoted in place as at 46 and approximately a three-quarter edge portion thereof is provided with gear teeth 48 which mesh with rack teeth 50 provided on the coordinated surface portion of the plunger rod. Therefore, the plunger means may be said to be operated by rack and pinion means or more specifically by a rotatable handle-operated gear having teeth meshed with teeth on the projectible and retractible plunger rod. Incidentally, the nose 52 (FIG. 2) of the rod is such that it registers with requisite nicety with the aligned end of the hinge pintle 18.

Although the gear operating handle may be of some other construction it preferably comprises a rod member 54 having a loop-like hand-grip 56 at an outer end. The other end portion is laterally offset at 58 where it is fashioned into a suitable foot 60, said foot fitting into a radial groove 62 and being suitably welded or otherwise secured in place. Obviously by rocking this gear handle or lever back and forth the gearing means is brought into play to properly actuate the plunger.

The numeral 64 designates a horizontal plate with the marginal flange 66 which said plate screwed or otherwise fastened in place as at 67. This flanged plate provides a tray which functions to trap or catch the dislodged pintle as shown in FIGS. 1 and 2. The central portion of an edge of the plate is notched as at 68 so as not to interfere with the operation of the device.

In practice the channel of the channel-shaped base is lined up with the leaves 8 and lit of the hinge means 6 as shown in the drawing. The channel is such in crosssection that the connected ends of the leaves 3 and 10 are covered thereby. However, it is necessary to shift the handle and the channel so that the notches 26 and 28 line up with the hinge knuckles '16 and i7 and the associated hinge pintle 18 in the manner clearly illustrated. All that is necessary now is to hold the base in position with the use of the outstanding handle 30 and to then operate the gear 44 by way of the lever or handle as to transmit motion to the plunger rod 34 by way of the cooperating gear and rack teeth. The nose 52 of the rod engages the registering pintle as is clear in FIG. 2 and the pintle is pushed out (in the manner depicted in FIG. 1) and trapped in the tray 64.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
